全站随机 tag ，仅查询最新创建的500个，不建议超过5000。可以放在任意地方，具体怎么发挥看大家了。样式 bootstrap 自行修改。
<?php if ('mysql' == $conf['cache']['type']) {
$taglist = well_tag_find(1, 500);
} else {
$taglist = cache_get('well-taglist-random');
if (NULL === $taglist) {
$taglist = well_tag_find(1, 500);
$taglist and cache_set('well-taglist-random', $taglist, 1800);
}
}
?><?php if($taglist){
$tagkeys = array_keys($taglist);
$tagtotal = count($tagkeys) > 20 ? 20 : count($tagkeys);
$randkeys = count($tagkeys) > 20 ? array_rand($tagkeys, $tagtotal) : $tagkeys;
